Backup power supply

ZZR series power units manufactured by A&M comprise complete DC backup power systems. Guaranteed 230V AC and 24V / 48V DC are optional.

A ZZR750 series power unit is equipped with a 1000 W buffered power supply, comprising 3 redundant modules, a battery with a 5 or 10 year lifetime, temperature compensation, full power supply state visualisation and alarm signals. Optional: earth fault control system, emergency power unit start under a power failure, operating mode selection under an earth fault, ventilation and heating module, cabinet temperature control, connection for digital signal transmission (RS 485), DC/DC 24V transducer, 1000VA inverter for guaranteed AC power supply.

A ZZR1000 series power unit is equipped with a 2000 W buffered power supply, permitting installation of a more powerful battery. Other features identical to ZZR750.

A ZZR2000 series power unit is equipped with an 11,000 W buffered power supply, a bank of VRLA batteries with a 5, 10 or 15 year lifetime, temperature compensation, full power supply state visualisation and alarm signals. Any power supply configuration is possible, e.g. two power supplies operating (redundancy) or powered directly from two separate AC grids.

Optional equipment: earth fault control system, COB monitoring, voltage spike / drop monitoring, communications computer, RS 232 connection, 230V AC inverter, DC/DC 24V or 48V transducer, cabinet ventilation and temperature control module, cabinet air conditioning DC and AC switchgear. MTB stands at more than 150,000 h.

Custom projects - power units, inverters, emergency lighting

We construct power supply equipment to satisfy unusual operating requirements, such as:

  • power units to operate in extreme working conditions: in industrial facilities with high concentrations of dust, extreme climatic conditions (down to minus 400C )
  • power units with AC and DC switch
  • suitable for MASTER - SLAVE redundant operation

We supply powerful inverters to test laboratories and production facilities for unusual voltages and frequencies, e.g. 110V and 60Hz.

We supply emergency lighting systems with a central battery supplying 12V, 24V, 48V, 60V to output circuits (historic sites, emergency lighting for old light sources, etc.)
